i use a large duffle bag for my KM (35"ish). and i seriously transport mine 3-4 times/week. i didn't wanna poke a hole in my nice bag, so i just set the hookah in at an angle (base and stem connected) and pack all my stuff in there and close the zipper to where the hookah sticks out to keep it from moving. i just remember to treat it VERY carefullly... it has glass afterall. I transport it in my car, walking, or on my motorcycle... they're durable so don't worry, but don't be careless either . sorry to contradict myself
